Describe the experiment conducted by Alfred Hershey and Martha Chase for identification of genetic material.

How did Alfred Hershey and Martha Chase arrive at the conclusion that DNA is the genetic material?

Define transformation in Griffith's experiment. Discuss how it helps in the identification of DNA as the genetic material.

In bacteriophage experiment, performed by Hershey and Chase, radioactivity in supernatant was due to

The Hershey and Chase's experiment using bacteriophage demonstrates.

Which of the following statements are false regarding 'Hershey and Chase' experiment, proving DNA is genetic material ? (i) They made use of rats. (ii) Radioactivity was seen in supernatant for the medium that was infected by phase radiolabelled with .^(32)P . (iii) Used radioisotope to label sulphur with .^(35)S in sulphur- containing amino acids. (iv) Radioactive phages were allowed to attach to E. coli bacteria.

Recall the experiment done by Frederick Griffith. If RNA, instead of DNA was the genetic material, would the heat killed strain of strep have transformed the R-strain into virulent strain? Explain your answer.

The experimental material used by hershey and Chase for proving that DNA controls heredity was (a) Escherichia coli (b) Salmonella typhimurium (c) T2 phage (d) TMV

In their side by side experiments Hershey and Chase incorporated ""^(35)S into

Recell the experiments done by frederick Griffith, Avery, MacLeod and McCarty, where DNA was speculated to be the genatic material. If RNA , instead of DNA was the genetic meterial, would the heat killed strain of pneumoccus have transformed the R-strain into virulent strani? Explain.

[A]: Hershey and Chase experiment showed that protein is the genetic material of T_2 bacteriophage. [R]: According to Hershey and Chase, RNA is the genetic material in T_2 bacteriophage.
